There are many ways to take a sample of breast
tissue, and ultrasound-guided breast biopsy is an accurate, fairly quick
method of analyzing breast irregularities without invasive surgery or exposure
to x-rays to locate the mass. The procedure uses high-frequency sound waves
to produce an image of internal tissue and organs. The ultrasound machine
uses the echoes of pulsing or continuous sound waves to depict the breast
tissue, without the use of radiation. Often a physician will suggest the
procedure after an ultrasound reveals a suspicious mass.
With the patient lying on her back or turned on her side, the radiologist will administer local anesthesia to the breast and, using an ultrasound probe to locate the abnormal tissue, guide a hollow needle into the mass to obtain tissue samples for analysis. The procedure usually takes about 30 minutes. Most patients report little to no pain during the procedure. Generally, patients are able to return to their normal routine the same day.
To prepare for the procedure, the physician may ask any patient taking aspirin or another form of blood thinner to stop three days in advance of the biopsy. Though it’s not necessary, a patient may want to bring a friend or family member to lend support and a ride home afterwards.
